From cb97914b04e7b587cf555ec5b1c69d61014f3378 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Fri, 11 Nov 2011 15:20:34 -0800 Subject: kbuild: Add support for installing generated asm headers Generated asm headers are supposed to live in arch/*/include/generated/asm, but objhdr-y expect them to live in the same directory they are generated in. Instead of trying to cut that particular Gordian knot, introduce genhdr-y that takes this into account; the sole user of objhdr-y, linux/version.h, should be migrated over at some later date.
